LIQUID-DISPENSING DEVICE.

To all whom it may concern:

Be it known that I, WILLIAM M. BYER, a citizen of the United States ofAmerica, and a resident of Jersey City, New Jersey, have inventedcertain new and useful Improvements in Liquid Dispensing Devices, theprinciples of which are set forth in the following specification andaccompanying drawings, which disclose the form of the invention which Inow consider to be the best of the various forms in which the principlesof the invention may be embodied.

This invention relates to liquid-feeding devices, as for the purpose ofdispensing liquid soap for toilet purposes.

The object is a device possessing the improvements hereinafterspecified, which shall be economical and convenient in operation, cheapin construction, easy of assemblage, compact in form and regular andefficient in its action of feeding predetermined quantities of liquid.

Of the drawings, Figure l is a vertical central section, and Fig. 2 afront elevation.

As shown in Fig. 1, the glass reservoir A for the liquid to be dispensedhas a metal casing B and contains a piston-cylinder G with containedpiston G, the cylinder or chamber C having a slot D substantiallythrough its length from a point just below the upper limit of the playof the piston, for the purpose of utilizing the cylinder-interior abovethe piston asadditional available reservoir-space for the liquid. Whendepression of piston G, as shown, causes an out-flow of liquid fromcylinder C, the liquid passes through a. pipe I constituting anintermediate riser-passage, to a gravity feed and splash eliminator tobe described. If the liquid were forced exterior to the entire apparatusdirectly by the piston pressure, it would be emitted with such force asto splash or spatter against the hand of the person held in positionbelow the bottom outlet Q to receive it, in a wasteful as well as anannoying manner. But here, not only is the riser-passage I always filledwith liquid by the automatic operation of a check-valve J, such as thecommon conical construction, but also, it is forced out of passage Iinto a gravity outlet K constructed with an en largement or hopper Kwith which passage I communicates, which serves to take up the splashand eliminate its occurrence outside Specification of Letters Patent.

the apparatus, by acting momentarily as a reservoir which has asplash-eliminating function as to the final exit of the liquid. Theliquid flows from K downward through K gently by gravity to and throughthe final outlet Q, and not under the piston-pressure, as Q and Kfurnish free upward access for air, and K may be open to the air in theupper part of the reservoir. This permits the hand of the user toreceive the predetermined amount of liquid which fiows out in a gentlestream without spattering or splashing. If desired, the cylinder C maycommunicate directly with K, either in the illustrated location of thelatter, (by reversing the direction of piston-action), or with thelatter located below the lower end of C, with the direction ofpiston-action shown. The riser-passage I has, however, a most usefulfunction in the illustrated construction and arrangement, and the latterin all its aspects, is the preferred embodiment of the invention. Thepipe K may extend down so as to discharge directly into outlet Q. Therelative construction of the parts, as well as their relativearrangement, is immaterial, provided that the described function isexeouted.

The advantage of retaining the function of the piston or its equivalentis to dispense a predetermined quantity of liquid. A cap F is providedas shown, having a downward projection F 4 fitting down into the top ofthe cylinder C and secured thereto. casing-top O may also be secured tothe cylinderC. Reciprocable in cap F, F is a bushing F secured to theupper part of pistonrod E. A handle or push button P is secured to theupper end of piston-rod E. Bushing F has a lower flange-portion Ffitting against the lower surface of cap-portion F this flange beingengaged by the upper end of helical spring N. The lower end of thespring rests on a collar M which is secured, as by soldering, to theinside of cylinder G. Thus the spring normally acts upwardly againstflange F 2 to hold piston G in position for operation, the cylinderbelow the piston being filled with liquid of a predetermined quantitydependent upon the location of the lower end of slot D. WVhen button Pis depressed to compress the spring, the piston-rod and piston are alsodepressed to force the liquid into pipe I, opening The q check-valve Jupwardly to force liquid throughout the length of said pipe. WVhen thehand pressure on button P is removed,

the liquid in the upper part of pipe I closes check-valve J downwardly,and the spring automatically raises piston G, the, liquid above G beingfree to be forced thereby through the entire submerged upper portion ofthe long slot D, to mingle with the liquid in the main reservoir outsideof cylinder G, whence it reenters said cylinder but below the piston andthrough the lower part of slot D. This keeps pipe I filled with liquidup to the check-valve J, and, as the latter keeps the portion of thepipe I above it continually filled with liquid, irrespective of theliquidlevel in reservoir A, the next operation of piston G will forceinto K an amount of the liquid which stands in the upper part of pipe Iwhich corresponds with the abovestated predetermined feed. Check-valve Jmay be operatively located approximately or substantially on a levelwith the lower face of piston G, so that by means of slot D, pipe I willbe filled up to the check-valve as long as there is enough liquid in themain reservoir to reach the lower face of the piston. The cap F may besecured to metal cover 0, or as shown, C, to which F is secured, may besecured to 0, so that cylinder C and pipe I and their interior parts maybe all removed at once, in case the pipe I is separable from K as shown.

The filling-inlet S in casing top 0 may contain at its lower part afloat-valve U to prevent overflow in filling. If desired, the gravityoutlet passage may be through a pipe K located in a space between A andB; but any suitable means may be employed. The top casing part 0, aswell as the bottom casing part L, may be, screwed as shown, re-

movably attached to main part B; part L having an internal flange'Lserving as a support for glass reservoir A. Main casingpart B is cutaway in front, as shown in Fig. 2, to permit inspection of interior ofglass reservoir A; or it may be complete if the reservoir is nottransparent. The entire apparatus may be laterally supported from thewall, as by bracket-j aws R; or the standard T may carry the bracket R.
